One precaution: You can't paint with it in cold weather. The chemical reaction that transforms the water solution into a durable finish will not take place if the temperature is below 50°. (Conventional oil paints don't stick well in cold weather, either.)
Also, when checking the paint, be realistic and don't ignore areas just for the sake of convenience. It will cost you more in time and money later. Typically if one area of the paint is cracked or peeling, then the paint on the entire car is suspect. Maybe the rest of the car just hasn't quite reached that point of decay, but it will shortly. So if you only fix areas that look bad, you'll likely find that you wasted a paint job when the other areas start to crack or peel in a year or two.
Following a European directive, the British paint industry has reduced VOCs in two stages, the second of which came into force in January last year.
Color can make a big difference in your life. I know from experience. Before I learned my right colors, I had a closet full of right and wrong colors. Of course, the colors did not work together and definitely did not coordinate. I had no idea of the difference that coordinated colors can make. Further, I had a drawer full of lipsticks some with gold undertones and some with blue undertones.
Once you figure out which position is prime and which position is spray, place the valve in the prime position and grab the primer hose. Point the primer hose in the empty bucket near the top and at an aproxx.45 degree angle from the side (the reason for this is that there is likely to be pressure still built up in the airless and when you first switch on the airless to prime it, paint will likely burst out of the primer hose and you don't want to have it go everywhere). Now turn the airless paint sprayer on and you will see that the airless is sucking up the new paint and pumping out the primer hose. At first you will typically see a cleaning solution come out followed by your paint. When you see your paint coming out switch over the primer valve to the other position and you will see the airless pumping paint into the main hose.
We've devised a simple, full proof way to determine whether you are Light or Deep. Look at your overall complexion, eye and hair color. On a scale of 1 to 10, with 1 being the lightest and 10 being the deepest, determine where you fit. So, a 1 would be the palest Nordic complexion with light blond hair. A 10 would be the deepest ebony skin tone and dark or black hair. So, for example: most Mediterranean and Middle Easterners have dark eyes and deep skin and are, therefore, Deep. Most Northern Europeans have blonde hair and light eyes and are Light. Where do you fall? Give yourself a number. If you fall anywhere from 1 to 4 then you are a Light. If you are 5 or greater you are on the Deep side.
